A new series of triple layered Ruddlesden-Popper compounds of the general formula (LixVO)La2Ti3O10, where X = 0.83, 0.93, 1.4 and 1.8, have been prepared. Lithium is intercalated into the layered perovskite in a reductive manner to produce new mixed valence compounds. The structure of the parent, (VO)La2Ti3O10, is maintained upon intercalation. Above a certain lithium content, the magnetic behavior of (LixVO)La2Ti3O10 changes from paramagnetic, for X = 0.83, 0.93, 1.4, to a magnetically ordered material for (Li1.8VO)La2Ti3O10.
